Sounds like a trip we took in 1994. I love the four corners area so much to see so little time.
Isn't it great to see the trailer getting hit by crosswinds and not feeling it in the cab.
When you installed the PP did you grease all the pivot points. My Hensley has a little bit of creaking and groaning when making tight turns. You also get some noise as you raise the jack and load up the spring bars. You can't use too much grease.
You can get a spare tire carrier that mounts under the a-frame. Obviously the rocket scientist that designed the setup you have has never been to the southwest. They sure do have some high curbs down there. I wore out a couple of sets of exhaust tips on my bike going down those steep driveway let downs coming out of gas stations.
